In the 1980s, Beverly Whipple and John Perry were teaching Kegel exercises to women with urinary stress incontinence. They identified a patch of tissue that can be felt through the front wall of the vagina, directly behind the pubic bone that they suggested might cause orgasm in some women. They published a book with Alice Khan Ladas: The G Spot: And Other Discoveries about Human Sexuality. The authors were not sex researchers.
The G-spot was named after Dr Ernst Gräfenberg, who wrote about the area in 1950. This was clever thinking because it implied symmetry between the sexes. Men were known to have a G-spot at the base of the prostate gland. But the anatomical parallels are erroneous. Women do not have a prostate gland, which probably explains their lack of interest in anal sex. Both homosexual and heterosexual men can obtain intense pleasure from anal stimulation, which is also used when a semen sample is required.
The only sexual anatomy that men and women have in common is the phallus (penis or clitoris). The male glands (including the prostate) develop from ducts that waste away in the female. As a result, a woman has very different internal reproductive anatomy to a man. So women do not ejaculate as men do. Similarly, the vagina (including the anterior wall) develops from ducts that waste away in the male. If women were capable of orgasm through stimulation of any part of the vagina, such a response would need to have evolved separately from the male orgasmic capacity. Yet there is no biological justification for women ever having an orgasm by any means.
The anatomy, the physical stimulation and the erotic turn-ons required for male orgasm are evident not only a man but also to his lover. By contrast, women’s responses are not such that men can divine the turn-ons and stimulation involved. That doesn’t stop men trying to guess. No one provides theories to explain how male orgasm occurs. To do so would highlight that women have equivalent anatomy as men and that women also might be capable of a similar response, not through stimulation supplied by men, but from stimulation that women are themselves motivated to provide.
Kinsey and Hite highlighted the indisputable arguments for the clitoris as the equivalent of the penis. Thereafter, researchers suggested that the clitoral organ is connected in some way or adjacent to the vagina. No one ever comments on the fact that men need much more direct stimulation for orgasm. A belief in vaginal orgasms is vital to men because it represents a means of justifying intercourse. The G-spot has succeeded for this reason.
The G-spot was a simple explanation that could be used to insist this goal was achievable. It provided political and emotional incentives for women, who know nothing of orgasm, to claim to orgasm in a way that pleases men. Most women are happy to accept that their orgasms rely on stimulation provided by men. For women who assume they orgasm as men tell them should, research backing the vagina gives their claims some authenticity.
Men can only engage in sexual activity when they have an erection. The satisfaction of men’s sexual needs (based on their territorial instincts) relies on ejaculating into a vagina. The ejaculation of sperm into the vagina is the key reproductive event. No one wants (nor is it usually comfortable) to continue stimulation once orgasm has been achieved. But given women provide an orifice, the principle is much less evident for women’s sexuality. There is no point during intercourse at which a woman refuses to oblige a man in attaining the goal of the activity, which is clearly male orgasm.
The G-spot was invented in 1982. But if the G-spot truly existed, it would have been discovered by heterosexual couples themselves rather than scientists. Heterosexuals reproduce by engaging in intercourse and yet in over 200,000 years of evolution, homo sapiens did not discover the G-spot. This is the political nature of sexology, which provides political ammunition for people’s emotional beliefs. It has been hugely popular despite the research being challenged as inadequate and being disproved by sexologists.
Other areas of science involve proposing theories that are then tested and supported by considerable evidence before they are accepted. Yet the G-spot (which has never been described as a theory) continues to be promoted despite widespread cynicism and contrary evidence. The G-spot is still actively promoted today after more than 30 years. It could never apply to every woman because the samples involved were so small. Yet the G-spot is talked about as if every woman can benefit from knowing about it.
In 2010 Andrea Burri did some research at Kings College, London. There was no physical examination. There were 3,000 women, pairs of identical and non-identical twins, who completed a survey. Among other questions, they were asked if they believed they had a small area on the front of the vagina that was sensitive to deep pressure. The study (the biggest of its kind to date) concluded that the G-spot as a well-defined area did not exist. Despite appearing in the Journal of Sexual Medicine, the findings have had little impact compared with the sensational success of the original theory.
All published scientific data indicate that the G-spot does not exist (and the female prostate has no anatomical structure that can cause an orgasm). (Vincenzo & Giulia Puppo 2014)
